The
2.80 firmware update causes the Guitar Hero instruments to connect to
the Playstation with a high controller number. As a result Guitar Hero
will not recognize the instrument at launch. To remedy this you will
need to change the controller assignment in the Playstation 3 XMB
system menu.

In the XMB go to Settings->Accessory Settings->Reassign
Controllers. From here you will be able to change the controller
number. Assign your first instrument to controller number 1 and
increment the controller numbers for any additional instruments that
you have connected. If you are using a microphone make sure to connect
a standard PS3 controller before launching the game.

I have the exact same problem. I played Rock Band 2 yesterday and it was working fine as always. I have 2 Les Paul PS3 controllers and 1 Guitar Hero 4 guitar controller and 1 GH4 drum controller. Later that evening I updated my PS3 to the new v2.8 and now I cant play RB2 or GH4 since when I connect ANY of my controllers I get 2 lights on all my controllers. My regular wireless hand held game controller (the one to use for the mic input) works fine but all the instrument based ones (guitar/bass/drum) now have the dreaded 2 lights sybcg issue and no they longer respond when pressing the colored buttons or start button to to start the game. Only the PS button works but that's it. HELP! I think PSN update v2.8 messed up the controllers.

The flashing lights on the controller mean the guitar is not connecting to the wireless usb dongle connected to the PS3.

1. Verify that the wireless box is plugged in firmly to the usb port on the front of the PS3.

2. If that doesn't work, look on the wireless usb dongle for the guitar hero guitar controller. (It should be a black box with the guitar hero logo on it. You will find a small push button on the dongle. (Make sure your PS3 is turned on, though your guitar hero game does not have to be open. It may be a good idea to have the game running, so you can test your guitar or make sure it is really working). Press and hold the button on the wireless usb dongle for a few seconds. Five seconds should be enough. Doing this attempts to re-connect the dongle and the controller. You will know when the connection is good when the red lights on the controller go steady, as well as the LED on the small button you pressed on the wireless usb dongle. If either lights continue to blink, there is a connection problem still.

check what number controler it has set to. Mine set to 7 for some reason. Go to control settings and change to the relevent numbered controler. Mine was 2 as it was the second device that i had linked to the ps3.

I've had the same problem, the guitars for this guitar hero are terrible, they were apparently rushed by Sony; ive researched the problem and apparently you can get a "dongel" or something, it's supposed to keep it connected, look into one.

It seems that the recent PS3 Firmware update (2.80) reassigns your controllers. In order to fix this (I just did it 20 minutes ago and all is fine) is:Go to the XMB "Settings" Menu.Open "Accessory Settings"Using the controller you want to reassign, open "Reassign Controllers"Scroll to the number you want that controller to be (1,2,3 or 4)You are good to go!
